BIRMINGHAM, Ala. -- A total of 50 points have been deducted from Chevrolet’s manufacturer championship total and Honda’s total has been reduced by 30 points for violation of engine sporting regulations.

The Nos. 11, 12, 17 and 20 cars with Chevrolet power and the No. 98 Honda-powered car were found to have violated rule 10.6.4 (non-minor engine repair). In accordance with the rule, 10 points will be deducted for an engine undergoing a non-minor repair that requires a component change, subject to INDYCAR approval. The engine will no longer be eligible for points from Rule 10.6.4.2.

Additionally, both manufacturers were found to have violated Rule 16.5.1 (engine change under mileage). Chevrolet switched out the engine in the No. 83 car before it met the 2,500-mile threshold, while the Honda engines in the Nos. 7 and 77 cars were changed out.

The members may contest the imposition of the penalties pursuant to the procedures and timelines detailed in the review and appeal procedures of the Verizon IndyCar Series rulebook.

Chevrolet leads the Engine Manufacturers’ Championship 197-112 heading into the April 27 Honda Indy Grand Prix of Alabama.
